Nuaire EcoSmart Connect (CO) control (XBOXER XBC, BPS, BOXER), 2026 object list BACnet points list

Updated 12 November 2026

Short answer

The EcoSmart Connect (CO) controller is a BACnet MS/TP device (default MAC address 4). This July 2026 manual lists 207 objects: AVs and multistate values in the 28501-28992 range (unit enable, software setpoint, fan speed command, sensor readings, up to eight RM room modules, configuration and alarms), four schedules and seven trend logs. The object numbering differs from Nuaire's 2022 list, so match the list to the unit's manual.

This page lists 207 BACnet objects for the Nuaire EcoSmart Connect (CO) control (XBOXER XBC, BPS, BOXER), 2026 object list — 119 of them writable — with each object’s type, instance number, name, engineering units and access. It is re-typed from Nuaire’s own free documentation, linked below.

BMS integration notes: Nuaire EcoSmart Connect (CO) control (XBOXER XBC, BPS, BOXER), 2026 object list

Integration in brief

Write MV 28511 Unit Enable to 1 (On) to run the unit, then set AV 28632 Fan Speed Command (0-100 %) and AV 28654 Software Setpoint (12-28 °C). Read the supply, fresh and return air temperatures, MV 28536 Fan Command and the alarm MSVs; MV 28660 resets alarms. Nuaire recommends writing AVs and MSVs at priority 16.

Minimum points to map

The short list most integrators start with — enough to run the unit from a BMS. Map more as the job needs.

Object	Name	Why	Access
MV 28511	Unit Enable	Unit enable (0 = Off, 1 = On)	Write
AV 28632	Fan Speed Command	Fan speed demand, 0-100 %	Write
AV 28654	Software Setpoint	Temperature setpoint from the network, 12-28 °C	Write
MV 28660	Reset Alarm	Alarm reset (1 = Reset)	Write
MV 28536	Fan Command	Fan enable output (OUT10) status	Read
AV 28501	Supply Air Temperature	Supply air temperature	Read
AV 28502	Fresh Air Intake	Fresh (outdoor) air temperature	Read
AV 28503	Return Air Temperature	Return air temperature	Read
MV 28538	Unit Fault Status	Fault relay status (0 = Alarm, 1 = Normal)	Read
MV 28664	Active Critical Alarms	Critical alarm active (1 = Alarm)	Read

Enable & remote start

The unit runs when any enable source is active: the Unit Enable MSV (local display or network), volt-free inputs, night cooling, the internal enable schedule, a fan speed override or a room module PIR. When the enable is removed the unit runs on for the run-on time.

Sensors & values from the BMS

MV 28612 Setpoint Operation picks whether the last changed setpoint wins, software only, or last changed with a timeout.

Network setup

BACnet MS/TP only; default MS/TP address 4 (AV 29506, range 4-127). Baud rate is MV 28507.
Device instance (AV 29505 Device OID) is unique from the factory.

Watch out for

Write AVs and MSVs at priority 16. Do not write outputs; if you must for testing use priority 8 and relinquish afterwards.
Priorities 8 and 16 survive a power cycle; other priority levels are cleared.
Instance numbers changed between Nuaire's 2022 and 2026 manuals; confirm against the unit.

Type: AI, AO, AV, BI, BO, BV, MI/MO/MV (multi-state) · Access: Read read-only, Write writable, Command writable with a priority array.

Note: the source document has no read/write column, so access here is inferred from the object type (inputs read-only, values writable). Confirm on the live controller before writing.

Integration notes

The list has no read/write column. Access here is inferred: sensor values, statuses, outputs, alarms and trend logs are R; enables, setpoints, commands and configuration are W.
Multistate values are printed with 0-based numbers (0 = Off, 1 = On); listed as printed. Check the live State_Text, since BACnet multistate values normally start at 1.
MV 28677 is printed twice, as PAC Board Alarm (BPS, reverse cycle DX only) and as Sensor Alarm; both rows are kept. IN16 CO2 Sensor (28512) and IN16 Temperature Sensor (28513) are printed as MSV with analogue ranges.
Rows repeated in the source (four schedules, RM200 temperature and humidity) were listed once; the device object row is left out.
RM199-RM206 are up to eight room modules on the controller's sensor bus; their objects only carry values when that module is fitted.
Nuaire's 2022 manual (672040) uses different instance numbers for many objects; that list is kept as a separate entry.

Check it against the live device. A points list tells you what the controller can expose; the unit in front of you may differ by firmware or installed options. This list is provided as-is for reference only and may contain mistakes — confirming it before you write, map or commission anything is up to you (terms). Easy BACnet scans a network for BACnet IP devices from an Android phone, reads every object on the EcoSmart Connect (CO) control (XBOXER XBC, BPS, BOXER), 2026 object list and exports what it actually has to Excel — free. New to BACnet? Start with what a BACnet points list is and what the object types mean.

Questions about the Nuaire EcoSmart Connect (CO) control (XBOXER XBC, BPS, BOXER), 2026 object list

How many BACnet points does the Nuaire EcoSmart Connect (CO) control (XBOXER XBC, BPS, BOXER), 2026 object list have?

This list has 207 BACnet objects: 85 analog values, 4 schedules, 111 multi-state values, 7 trend logs. The exact set on a given unit depends on its firmware, installed options and configuration.

Which Nuaire EcoSmart Connect (CO) control (XBOXER XBC, BPS, BOXER), 2026 object list BACnet points are writable?

119 of the 207 objects accept a write. Points marked Command have a priority array: a write holds until it is released, so release it back to automatic when you are done. The source has no read/write column, so this is inferred from object type.

Where is the official Nuaire EcoSmart Connect (CO) control (XBOXER XBC, BPS, BOXER), 2026 object list BACnet documentation?

The source is Ecosmart Connect (CO) Control Operation Manual, BACnet object list (672059), revision 2026-07-27, published free by Nuaire at https://info.nuaire.co.uk/IandM/672059.pdf.

What are the minimum BACnet points to integrate the Nuaire EcoSmart Connect (CO) control (XBOXER XBC, BPS, BOXER), 2026 object list?

Start with MV 28511 Unit Enable (Unit enable (0 = Off, 1 = On)); AV 28632 Fan Speed Command (Fan speed demand, 0-100 %); AV 28654 Software Setpoint (Temperature setpoint from the network, 12-28 °C); MV 28660 Reset Alarm (Alarm reset (1 = Reset)); MV 28536 Fan Command (Fan enable output (OUT10) status); AV 28501 Supply Air Temperature (Supply air temperature); AV 28502 Fresh Air Intake (Fresh (outdoor) air temperature); AV 28503 Return Air Temperature (Return air temperature); MV 28538 Unit Fault Status (Fault relay status (0 = Alarm, 1 = Normal)); MV 28664 Active Critical Alarms (Critical alarm active (1 = Alarm)).

How do I enable BMS control of the Nuaire EcoSmart Connect (CO) control (XBOXER XBC, BPS, BOXER), 2026 object list?

Can the BMS supply sensor values to the Nuaire EcoSmart Connect (CO) control (XBOXER XBC, BPS, BOXER), 2026 object list?

MV 28612 Setpoint Operation picks whether the last changed setpoint wins, software only, or last changed with a timeout.

How do I check these points on the real EcoSmart Connect (CO) control (XBOXER XBC, BPS, BOXER), 2026 object list?

Scan the network with a BACnet IP browser such as Easy BACnet, open the device and compare its object list with this table. Anything missing is usually an option that isn't installed or a point that is disabled in the controller's configuration.
